Code:

/bin/find /path/tofile -name filename.whatever  -size +10485760c > ./big.dat
if [[ -s ./big.dat ]] ; then
     big.dat > /usr/bin/mailx -s 'file too big '  usename@foo.com
fi

You have to enter this into cron to run, say, every five minutes. If you want it checking constantly.

what I'm looking for is, as i said i have serveral files (*.txt) under the /var/opt/abc. if any of the file increased to more than 1mb, then i wanna send a mail with increased file name and size. Thanks once again.

Yes,
/path/tofile => /var/opt/abc
filename.whatever => "*.txt"

Thanks for your reply.

I just tried with the script which you give me and it did work with some changes. I modified the script like below

find -name core.* -size +10485760c > ./big.txt
#if [[ -s ./big.txt ]] ; then
#big.txt > /usr/bin/mailx -s 'file too big ' abc@xyz.com

this works but I want to see file size too like this..
-rw------- 1 root root 254517248 Aug 4 21:36 core.2909 and this line i wanna send as a mail.

when I tried with this...

/bin/find /path/tofile -name filename.whatever -size +10485760c > ./big.dat It says couldn't find the /bin/find.

Thanks for your help.

try this....

ls -lrt|awk '$5 > 10485760 {print}' > ./big.txt
if [[ -s ./big.txt ]] ; then
/usr/bin/mailx -s 'file too big ' abc@xyz.com < big.txt
